Methods of Batching Concrete
To make 1:1:2 ratio concrete mix according to volume batching, one should take one bag of cement (35 liters) , 1 gauge box of fine aggregate (35 liters) and 2 gauge boxes of fine aggregate (70 liters). If the water-cement ratio is 0.5, then half of the volume of cement which is 25 liters of water should be taken.
Material mix design for masonry grouting
Refer to the manufacturer to be sure the material mix design is compatible with the delivery system. As stated earlier, masonry grout pump manufacturers often provide a pre-approved mix design including compressive strength and proportions of each component. These mix designs can be used to order from ready-mix providers or to batch onsite.

VOLUME BATCHING OF CONCRETE – THEORY & EXAMPLE CALCULATION
Jun 17, 2016 · Step-1-Batching of cement. Cement is always measured by weight. Mostly it is used in terms of bags. One bag of cement weighs 50 kg and has a volume of 35 litres (or, 0.035m 3 ). Cement should not be batched by volume because its weight per unit volume varies according to the way the container is filled.
